This is how red blood cells look under light microscope.
It is not exactly red.
It is pink.
Remember that red blood cell don’t have nucleus but the white ones have ……….
The ones that are circulate and pink colors are the red blood cell, the other that have purple nucleus are white blood cell.

under a microscope you can easily distinguish red blood cells from white blood cells. If you stain your blood with the May-Greunwald-Gemsa coloration you can even distinguish different WBC from each other. Trust me, i have done it personally...

That picture is of a slide stained with hemotoxin and eoisin.. Red blood cells do not look red under a microscope without a stain. I would suggest doing the same stain.. very easy, all you need is some xylene, ethanol and H and E..Once you have stained your sample, WBC are bigger and nucleated. The picture shows a lymphocyte and what looks like a monocyte in the lower half of the screen.

Hello Dear, I am from Regulatory T Cells. Assuming you're looking at human erythrocytes, they look like a doughnut but with a very thin center instead of a hole. Depending on the power of your microscope and the amount of light, they will be darker toward the outside and light/translucent at the center.

The blood consists of a suspension of special cells in a liquid called plasma. In an adult man, the blood is about 1/12th of the body weight and this corresponds to 5-6 litres. Blood consists of 55 % plasma, and 45 % by cells called formed elements.
